HENRY W. VAN LEIR, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO S. S. WEN- ZELL MACHINE COMPANY, OF CHARLESTON, WEST VIRGINIA, A CORPORATION OF WEST VIRGINIA.

BRUSH FOB BOTTLE-WASHING DIACIIINES.

T 0 all whom it may concern:

Be it known that I, HENRY V. VAN Lnm, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Brushes for Bottle- IVashing Machines, of which the following is a specification.

My invention relates to that type of bottle-cleaning brushes which consists of a rubber tube comprising a socket for application to a nozzle 011 the brush-carrying spindle and a plurality of projecting fingers, also of rubber, which are free to spread apart under the action of centrifugal force as the spindle is rotated, so that they will conform to the interior of the bottle and contact with the sides and bottom ofthe same, longitudinal movement being imparted to the brush or bottle so as to cause said brush to contact with all parts of the interior of the bottle.

The object of my invention is to so construct such a brush as to facilitate the spreading of the fingers and to prevent the cutting off of the fingers by pressure of the bases of the same against the metal nozzle on the brush-carrying spindle. This object I attain in the manner hereinafter set forth, reference being had to the accompanying drawing, in which Figure 1 is a vertical sectional view on the line aa, Figs. 2 and 3 of a bottle-cleaning brush constructed in accordance with my invention; Fig. 2 is a horizontal section on the line b?), Fig. l, and Fig. 3 is a horizontal section on the line cc, Fig. 1.

In the drawing, 1 represents the head applied to the top of the brush-carrying spindle, this head having a projecting threaded nozzle 2, and both head and nozzle being tubular in order to permit of the flow therethrough of the water supply for the brush. The latter is made of rubber and consists of a tubular base or socket 3, a series of projecting fingers 4c, and a tubular portion 5 intervening between the socket and the fingers and provided with a series of slots 6. Each of the fingers 4 is of segmental form in cross section and has, at its outer end, a bulb or button 7 whereby the weight of the outer end of each finger is increased and its susceptibility to spread under the action of, centrifugal force, thereby augmented, freedom of spread of the fingers being further insured by decreasing the Specification of Letters Patent.

cutting of said fingers at the base when, by

reason of end pressure exerted upon them, they are forced into contact with the metal nozzle. The elasticity of the member 5 of the brush arises from the fact that its walls are thin as compared with its length, so that when subjected to endwise or longitudinal pressure, said walls will buckle or bulge outwardly and will thus fail to offer a rigid resistance to the longitudinal thrust of the fingers. YVhile slotting of this intermediate member 5 of the brush is not necessary it is preferred, because such method of construction serves to increase the elasticity of said member. The walls of this intermediate member may, however, be thinner than the fingers or the walls of the socket, if desired.

I claim:

1. A rubber brush for a bottle Washer, said brush comprising a socket, a series of spreading fingers, and an unconfined tubular member interposed between said socket and the bases of the fingers, the Walls of said tubular member being relatively thin, whereby it is free to expand laterally when end pressure is exerted upon it.

2. A rubber brush for a bottle Washer, said brush comprising a socket, a series of spreading fingers, and a tubular member in-' terposed between said socket and the bases of the fingers, said interposed tubular member being provided with slots.

8. A rubber brush for a bottle-washing machine, said brush comprising a socket, and a series of projecting fingers having, at their outer ends, internal bulbs or buttons whereby said outer ends are rendered more susceptible to the action of centrifugal force.

4. A rubber brush for a bottle-cleaning machine, said brush comprising a socket, and a series of projecting fingers, said fingers being decreased in thickness at or near the base, whereby they are rendered more susceptible to spreading under the action of centrifugal force.

5. A rubber brush for bottle cleaning-machines, said brush consisting of a socket, and a series of projecting fingers having bulbs or buttons at their outer ends, said fingers being decreased in thickness at or near the base.

6. A rubber brush for bottle-cleaning machines, said brush consisting of a socket, a series of fingers, and an interposed tubular member beyond the end of the socket, said fingers having internal bulbs or buttons at their outer ends.

7. A rubber brush for bottle-cleaning niachines, said brush consisting of a socket, a

series of fingers, and an interposed tubular member, said fingers being decreased in thickness at or near the base.

8. A rubber brush for bottle-cleaning machines, said brush consisting of a socket, a series of fingers, and an interposed tubular member, said fingers having bulbs or buttons at their outer ends and being decreased in thickness at or near the base.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing Witnesses.
